fsl_diu_fb: fix build with CONFIG_PM=y, plus fix some warnings

This patch fixes following build error when CONFIG_PM is set.

  CC      drivers/video/fsl-diu-fb.o
drivers/video/fsl-diu-fb.c: In function 'fsl_diu_suspend':
drivers/video/fsl-diu-fb.c:1327: error: 'ofdev' undeclared (first use in this function)
drivers/video/fsl-diu-fb.c:1327: error: (Each undeclared identifier is reported only once
drivers/video/fsl-diu-fb.c:1327: error: for each function it appears in.)
drivers/video/fsl-diu-fb.c: In function 'fsl_diu_resume':
drivers/video/fsl-diu-fb.c:1337: error: 'ofdev' undeclared (first use in this function)

While I'm at it, also fix this warning:

drivers/video/fsl-diu-fb.c: In function 'fsl_diu_alloc':
drivers/video/fsl-diu-fb.c:314: warning: format '%lx' expects type 'long unsigned int', but argument 3 has type 'phys_addr_t'

And these section mismatches:

..from the function fsl_diu_remove() to the function .exit.text:uninstall_fb()
..from the function fsl_diu_remove() to the function .exit.text:uninstall_fb()
..from the function install_fb() to the variable .devinit.data:fsl_diu_mode_db
..from the function install_fb() to the variable .devinit.data:fsl_diu_mode_db
..from the function fsl_diu_probe() to the function .exit.text:uninstall_fb()
..from the function fsl_diu_probe() to the function .exit.text:uninstall_fb()

Also, some sparse fixes: make two functions static, and use NULL where
appropriate. There are still a lot of sparse warnings, mainly wrt absence
of __iomem annotations, but some will require ugly __force stuff. I'll leave
them for now, since proper fix would be not that trivial as few one-liners
below.
